The extra I is back titrated with thiosulfate S2O If vitamin C, which is a good reducing agent, is present, the blue dye, which turns pink in acid conditions, is reduced to a colorless compound by ascorbic acid. However, even if we slightly overshot the end point the concentration of the vitamin c we determined should almost be correct and should not affect our final result in so far that it would lead to another assumption about what fruit would be best to take.
